1. Flowserve Completes Engineering for Concentrated Solar
Power (CSP) Plants in Africa
Flowserve has completed engineering and is now heavily engaged in manufacturing key pumping
systems for the Ouarzazate and Bokpoort Concentrated Solar Power (CSP) projects.
Flowserve Corporation (NYSE: FLS), a leading provider of flow control products and services for the
global infrastructure markets, announced that it has completed engineering and is now heavily
engaged in manufacturing key pumping systems for the Ouarzazate and Bokpoort solar energy
projects.
Manufacturing is underway at Flowserve facilities in Coslada and Arganda, Spain and Desio, Italy.Â
Orders for these pumps were booked in prior periods. Located in Morocco, the 160-megawatt
(MW) Ouarzazate Concentrating Solar Power (CSP) Complex is the first phase of a larger project.
Utilizing the same design, the 50-MW Bokpoort CSP Independent Power Project is located near
Groblershoop, South Africa.
Both projects are CSP plants that focus the sun's energy on mirrors shaped like parabolic troughs.
Heat transfer fluid is pumped through a glass tube at the center of the parabolic troughs to absorb
solar energy. The heat from the high-temperature fluid is then used to generate steam to power a
standard steam turbine, which generates electricity, and partially transferred to molten salt storage
tanks during the peak solar radiation periods to extend the electricity generation. The Ouarzazate
project will have enough molten salt storage to allow operation up to 3.5 hours after sunset, while
the Bokpoort project will allow operation up to 9 hours after sunset.
The Flowserve pumping systems at the heart of these two CSP plants use heavy-duty, radially split,
between bearings pumps for heat transfer fluid (HTF) and vertical turbine pumps for molten salt
service. The HTF pumps use variable frequency drives designed to regulate pump speed and
optimize the efficiency of the system at elevated temperatures and pressures. These large double
suction pumps are engineered to meet ISO 13709/API 610 (BB2) standards. In addition to the HTF
and molten salt services, Flowserve also booked the boiler feed water, condensate extraction,
cooling water and auxiliary HTF pumps.
"As a pioneer in many of the significant advancements in pumping technology for the power
generation industry, Flowserve's extensive experience in high-temperature pumping applications
and our history of supplying equipment for solar power plant projects of this magnitude were crucial
factors in winning these orders," said Jim Quain, President, Flowserve Sales Organization. "Also
important was our ability to supply the entire project's pumping needs as well as our full line of
services, including installation, start-up and lifetime maintenance."
Both projects are owned by ACWA Power. Engineering and construction for Ouarzazate is being
performed by a Spanish consortium comprised of TSK, SENER and ACCIONA and for Bokpoort by
TSK, SENER, ACCIONA and CROWIE Concessions.

ACWA Power International (ACWA waste water Power) is a developer, investor, co-owner and

desalinated water with an investment value xylem water systems in excess of USD 22 billion and
providing employment to more than 2,400 people.The company, incorporated in the Kingdom of
Saudi Arabia, with a paid-up capital of approx. The majority of installed pumps were not originally
sourced for their present use. Frequently, a line in a facility changes and the pump that once
providedcooling water to an injection molding machine is now needed to move oil from a rail car to a
tank. Sadly, this leads to numerous problems for the pump and the plant. Pumps operate where the
pump curve crosses the system curve. When you relocate a pump from one system to another, this
means that the system curve is different. This new system may cause the pump to operate away from
its best efficiency point, leading to vibration and other component failures that are merely symptoms
of a mis-matched pump and system.USD 1.4 Billion is owned by eight Saudi conglomerates besides
Sanabil Direct Investment Company (owned by the Public Investment Fund) and by the Saudi Public
Pensions Agency. ACWA Power's core business is the delivery of electricity and desalinated water by
operating assets in which the company has a meaningful level of investment to exercise operational
control.
